F. MATTHEWS COMBER GUARD FOR LOOMS Filed Aug. 27, 1955 Invenlor A Home}:

Patented Apr. 20, 1937 UNITED STATES PATENT OFFICE Application August 2'7,

2 Claims.

This invention relates to improvements in Jacquard looms of the label type, such as shown in Patent #786,237 to Schaum, the general object of the invention being to provide means whereby the comber boards of the loom can be adjusted 0 at any desired angle so that the harness cords can pass through the holes or" the boards with a minimum amount of friction, thus preventing breaking of the cord and the wearing of the holes in the boards.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accom- H panying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding 7) parts throughout the several views, and in to which:

Figure 1 is a fragmentary View showing how a board can be adjusted at an angle to reduce friction from the cords as they pass through the holes W of the board. Figure 2 is a vertical sectional view through the loom comber board rails and showing the boards and the supporting means in edge View. Figure 3 is a top plan view of Figure 2. Figure 4 is a section on the line -5-4 of Figure 3. Figure 5 is a section on the line 5-5 of Figure 4. In the drawing the numeral 8 indicates the comber board rails of the loom which are provided with guide grooves for receiving the inwardly extending strips or guides 2 and in carrying out my invention I provide the supporting members or brackets 3 for the comber boards 4. Each bracket has a head 3 and a groove 3 in its inner edge, the groove receiving the boards and the 40 heads having threaded holes therein for receiving the set screws 5 which clamp the boards in the brackets in adjusted longitudinal position, a pair of these screws engaging the boards adjacent the side edge thereof as shown more particularly in Figure 3. A pivot rod 6 passes parallel adjacent the other edge of each board and this rod passes through the members 3 into the strips or guides 2 so that the boards and the members or brackets 3 are pivotally connected to the rails. It will be understood that a pair of these members or brackets 3 is provided for each board. Set screws 1 pass through the outer portions of the heads of the members or brackets 3 and these 1935, Serial No. 38,096

screws are located adjacent the screws 5 and engage the strips or guides 2 so that by adjusting these screws l the brackets 3 can be tilted on the rod 6 to adjust the slant of the boards l as shown in Figure 1, to suit the individual harness sections 5 of the loom harness.

Thus by means of this invention each comber board can be set at any desired angle to reduce friction of the cords of its respective harness section 8 through the holes 9 of the boards which results in reducing wear and breaking of the cords and also wear of the walls of the holes, the comber board for each harness section being set so as to extend perpendicular to the cords thereof.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:-

1. In a loom, a comber board, a pair of comber board rails with grooves therein, a pair of guides slidable in said rail grooves, pivotal supporting means extending between said guides and supported thereon, a pair of brackets pivoted on said supporting means, each bracket being adjacent its respective guide, fasteners carried by said brackets for engaging the end portions of said comber board for retaining and supporting the latter so that the same extends between said brackets, and screws threaded through said brackets and engaging said guides for angularly adjusting said brackets about their pivotal supports.

2. In a loom, a comber board, a pair of comber board rails with grooves therein, a pair of guides slidable in said rail grooves, pivotal supporting means extending between said guides and supported thereon, a pair of brackets pivoted on said supporting means, each bracket being adjacent its respective guide, said brackets having grooves therein for adjustably supporting the comber board extending therebetween, screws threaded through said brackets and engaging said guides for angularly adjusting said brackets about their pivotal supports, and additional screws threaded through said brackets and engaging said comber board for retaining the same in fixed position in said bracket grooves.
